Probably another simple VLAN / DHCP request

[katakuri]

I have a new Netgate 4200 that I am trying to get set up with a VLAN. I was following guides from all over and they didn't work so I wiped that stuff out and tried again. I have my WAN on Port 1 and my regular LAN on port 2. I m trying to set up a VLAN on port 4 for my IoT stuff. I can set up a DHCP server directly on PORT 4 and that works. I turned that off and tried creating stuff again:

Create VLAN:
-- tag 77
-- description IoT

Interface Assignments:
-- Assign to IoT igc0 and renamed to IoT
-- Enabled
-- Static IPv4
-- 10.77.0.1/16

DHCP Server:
-- Enable DHCP on VLAN IoT
-- Address Pool Range: 10.77.5.100 - 10.77.8.100

PORT4 (igc0) is enabled but no DHCP server assigned.

When I am done with that I plug a computer into Port 4 and no dhcp address ever happens. I run packet capture for UDP 67,68 and never see a peep.

Edit: Port 3 is enabled but the IPv4 configuration type is set to None. Is that correct?
